Abstract
Voice over IP (VoIP) is increasingly replacing fixed line telephone systems globally due to lower cost, call quality improvement. More and more application improvement and Video communication is emerging as an alternative to traditional public communication. End-to-end QoS for large Enterprise consists of three general areas: cutomer premises QoS (‘LAN QoS’), Service Provider (SP) core network QoS (‘WAN QoS’), and internetwork between them [1]. By implementing per-class architecture, we provide service guarantee in customer premises QoS (‘LAN QoS) for Open Lesson Real-Time. Skype is the most popular audio/video communication platform for end customers, providing over 500 million user on PCs and other devices. Through implementing Skype on Open Lesson Real-Time on Cianjur, we measure the transmission data, packet loss, and end-to-end voice and video delays through the best-effort Internet. Our result can be used to guide the design of Internet service for implementing Skype on Open Lesson Real-Time on Cianjur. © 2013 IEEE.
